When I heard that Karen Yuzuriha, the girl I'd admired since school days, had married my senior, I was so shocked I drank too much and ended up staying overnight at my senior's house. When I woke up, Karen and I were alone—my senior was away on a business trip. As she gently served me miso soup in light clothing, her warmth made my rationality vanish completely. Unable to hold back, I attacked her and had creampie sex. Maybe she had sensed my feelings all along—she accepted me. For the next three days, undisturbed by anyone, we ate, had sex, slept, then had sex again. Like animals driven by instinct, we satisfied our desires endlessly. This forbidden cohabitation became an unforgettable experience for both of us.
